I found a used 13 x 19 Mercury prop but the outer housing had a chip in it. Will that cause any issues? Just looking for a spare prop for my 90 hp optimax.
I did end up buying the prop. It looks like it had been repaired and on one blade it had a small bend on the outside edge. But overall it looked pretty good. Could tell it was repainted. I ended up getting it for $50 but had to drive an hour to get it.
Looks like that would be fine for a spare. I don't bother getting props repaired anymore, I just buy new ones. As others have mentioned its around $75 to repair a prop and for my 50 hp merc i can buy a new prop for around $115 and have it in 2 days from amazon. I found repaired props don't last long and are weaker. Also looking at a 2 week turn around in most cases.
Looks like a good $50 spare prop to me.
The seller is asking $60. Looking at the photos does that sound like a good deal? It does include the hub.
That little ding on the rim of the exhaust hub will not affect anything, especially on a spare prop! The blades are what your concern is. That hub is close to the prop shaft (less affect on balance while spinning) and does not have any effect on the actual propulsion of the boat. A chip out of a blade is farther from the center of the prop shaft and when combined with the difference in surface area in contact with the water, the balance of the prop is thrown off due to metal missing on the blade AND the difference in surface area contacting the water. That little chip out of the hub will affect nothing.
Fixing a prop is minimum $75. That prop new is $105-110 (I know, I bought 3 last summer same size-different pitches).
Wish I could comment on your specific issue...I cannot.
You can take it in and they will surely fix it for very little. I just had a totally beat up prop get fixed at All Out Marine for about $75? It was for my 25 horse Merc.
I know dings in the blades can cause disturbance under the water. Just didn't know if a chip in the round had the same effect.
You won't get optimal performance with it but it will push you forward. I've seen worse. That would be fine as a spare.
Edit: I was just looking at the blades. I re-read your post and so I'm not sure what issues the chip in the outer housing might cause. I don't think any, but I'm not the most mechanically inclined.
